Why is it essential to check for pest infestations during a commercial inspection?

Checking for pest infestations during a commercial inspection is essential primarily to prevent structural damage and health hazards. Pests such as termites, rodents, and insects can cause significant damage to the building's structure, leading to costly repairs and safety concerns. For instance, termites can weaken wooden structures, while rodents might gnaw through electrical wiring, creating fire hazards.

Moreover, certain pests can pose health risks to occupants. For example, rodents can carry diseases, and some insects can trigger allergic reactions or spread infections. Identifying and addressing pest issues during an inspection helps ensure a safe and healthy environment for tenants and employees, ultimately protecting the property's value and longevity.

The other options focus on aspects such as aesthetic appeal, energy efficiency, and beautification standards, which, while important in their own right, do not directly relate to the immediate health and safety concerns associated with pest infestations. Thus, the most critical reason for inspecting for pests is the prevention of structural damage and health hazards.
